MSH: Forms of hereditary angioedema that occur due to mutations in the gene for COMPLEMENT C1 INHIBITOR PROTEIN. Type I hereditary angioedema is associated with reduced serum levels of complement C1 inhibitor protein. Type II hereditary angioedema is associated with the production of a non-functional complement C1 inhibitor protein.,NCI: Autosomal dominant inherited disorders characterized by abnormalities of C1 inhibitor. Patients present with swelling of the skin, subcutaneous tissues, and mucosa sites. In type I hereditary angioedema, the plasma levels of C1 inhibitor are decreased. In type II hereditary angioedema, the C1 inhibitor is dysfunctional and its plasma levels may be normal or elevated.
